Application filed September 19, 1904- Selltl N0 224.985

Be it known that I, GEORGE P. HEM- sTREET, a citizen of the United States, residing at IIastings-upon-Hudson, county of l/Vestchester, and State of New York, have invented an Improvement in Measuring Apparatus, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates to means for conveniently measuring and portioning out material.

In the embodiment hereinafter to be described the invention is applied to the measuring of materials for thel manufacture of composition paving blocks.

In the manufacture of such blocks it is essential that the ingredients thereof shall bear certain definite proportions to each other, and to this end the present invention contemplates the use of a measuring vessel, preferably of variable capacity, to which the material, such as finely crushed stone, may be fed in a convenient manner, and means whereby the supply of material to the vessel may be readily cut off, while at the same time the contents of the vessel are retained therein, and also means whereby the vessel may be discharged of the previously determined quantity of material.

The invention further contemplates means in conjunction with the aforesaid apparatus for indicating that the vessel has reached its full capacity.

The above and other features of the inventionwill be clearly understood from a description of one particular embodiment thereof, which illustrates the best form now known to me, and which is shown in the accompanying drawings, in which,-

Figure 1 is a longitudinal, vertical section of the device partly broken away to more clearly show the interior structure, the apparatus being here shown in conjunction with a mixing device designed to be supplied therefrom; Fig. 2 shows a front elevation of the measuring device with parts removed to indicate the interior structure.

In the embodiment of the invention which has here been selected for illustrative purposes, the apparatus consists of a measuring vessel 1, comprising the telescoping members 2 and 3, the upper member being slidable within the lower one to avoid obstruction to the discharge of the vessel. The upper end of the vessel is provided with an opening 4 to receive material from any convenient source and below the opening 4 is a deflector plate 5, which serves to direct the material to the inlet opening 6 of the measuring vessel. The inlet opening 6 is controlled by a gate 7, here shown as a plate, which rests and slides upon the guide-ways or supporting brackets 8 on either side of the vessel. The lower or discharge end of the vessel 1 is also provided with a deflecting plate 9, which directs the material to be discharged to the discharge opening 10, which, as in the case of the inlet opening, is controlled by a gate 11 supported and slidable along similar ways 12.

In order to conveniently direct the contents of the vessel to a desired point, the lower end thereof may be provided with a suitable spout 13. The gates 7 and 11 controlling the inlet and outlet openings, respectively, of the vessel are herein shown as actuated through the instrumentality of levers 14, which are centrally pivoted upon brackets 15 attached to either side of the lower section of the vessel 1. The upper and lower extremities of the levers 14 are connected with the inlet and outlet gates 7 and 11, respectively, by means of pivoted links 16 extending between the extremities of the levers and the hinge members 17 attached to said gates. For convenience of operation the levers 14 are connected by means of the links 18 with rock arms 19 mounted upon the rock shaft 20, to which also is secured at any convenient point, as at the center, a hand lever 21 extending within convenient reach of the operator. At the upper end of the vessel 1 and adjacent the inlet opening 6 thereof is provided a sight hole 22, which is normally closed by a weighted sliding door 23, the latter in turn being provided with a suitable actuating cord 24 passing over suitable pulleys and extending within convenient reach of the operator.

The measuring apparatus may be stationed at any convenient point with relation to the mixing machine, the latter being here represented merely for the purposes of illustration as a vessel 25 provided with suitable mixing apparatus 26 and discharging into a IOO convenient chute 27, whereby the mixed material is led to a conduit 28, and thence into a suitable press where the composition blocks are finally formed.

The operation of the measuringapparatus is as follows: With the inlet and outlet gates in the position indicated in fullllines in Fig. .1, the material to be measured is turned into the vessel and is deliected by the plate 5 to the inlet opening 6. The operator from time to time lifts the gate 23, thus uncovering the sight hole 22 in order to determine the level ofthe material within-the vessel. When I'the vessel is 'filled to a point above ythe opening 6 yand above the sight lhole 22, va small portion of the material will Ybe discharged `through the sight hole, thus indicating that the ymeasuring vessel is filled to its full capacity; thereupon the yoperator by actuating fthe lever 21 Amay close the inlet 6 by meansof lthe gate 7 and shutoff the further supply of material. The gates y7 and 11 are made of such length that it is possible to close the upper or inlet opening before the gate 11 uncovers the outletopening 10, whereby lthe measured quantity of material maybe retained within the vessel ready for discharge at any convenient time. Upon continued lactuation of l[the 'lever 21 the gate 11 `will be further withdrawn until it uncovers the -discharge o ening 10, the ygate 7 at lthe same vtime retaining the inlet opening closed. `Furthermore, by arranging the inlet and outlet openings at one side of the vessel,fit is possible to perform lthe operations above described with gates of minimum length.

The sections 2 and 3 of the vessel 1 lmaybe connected in any-desired manner, butas here shown 'they are adjustably vconnected by means -of bolts 29 taking through lsecuring lugs 3'0 attached tothe sections. j

In order that the vessel may be adjusted to a fgiven capacity, the bolts 29 may be threaded through the lower lugs 30, and after adjusting the vessel to the required length, the latter maybe held at such adjustment by set :nuts`31.

It is -to be understood that the apparatus herein described represents fbut one embodiment of my invention and is susceptible of many changes, 'both `in the construction and relative arrangement of the parts, without departing from 'the spirit and scope thereof.
